Method for utilizing buffer strip to control agricultural non-point source pollution of tidal river network area of plain

Abstract

The invention relates to a method for utilizing a buffer strip to control agricultural non-point source pollution of a tidal river network area of a plain, belonging to the technical field of environmental protection. The method comprises the following steps of: selecting buffer strip areas, carrying out primary treatment to the buffer strip, setting a water distribution system of the buffer strip, selecting and planting plants in the buffer strip and introducing water source into the buffer strip. The method has the characteristics of simpleness, convenience, practicability, good purifying effect and free maintenance management.

Description

technical field

[0001] The invention relates to a method in the technical field of environmental protection, in particular to a method for controlling agricultural non-point source pollution in plain tidal river network areas by using a buffer zone. Background technique

[0002] The full name of the buffer zone is the protective buffer zone. It refers to the zone where the plant community near the river, including its composition, plant species and soil moisture, is obviously different from that of the highland vegetation. It is affected by both the water body and the land system, and has obvious edge effects.

[0003] Buffer zone is a type of ecotone between terrestrial ecosystem and aquatic ecosystem, and it is one of the components of wetland. It plays an important role in coastal ecosystem and has high ecological, social and economic value. The coastal buffer zone takes vegetation as the main symbol of its existence. Vegetation in the buffer zone not only plays the role ...
